Description
Die Erfindung bezieht sich auf gemischverdichtende, mit Fremdzündung arbeitende Einspritzbrennkraftmaschinen. Bei derartigen Brennkraftmaschinen ist es bekannt, zur Bildung eines zündfähigen Gemisches einen Kraftstoffstrahl durch den Brennraum hindurch in die Nähe der Zündeinrichtung zu spritzen. z. B. auf eine dort angebrachte Prallplatte.The invention relates to mixture-compressing, spark ignition working internal combustion engines. In such internal combustion engines it is known to use a fuel jet to form an ignitable mixture to inject the combustion chamber into the vicinity of the ignition device. z. B. on a baffle plate attached there.
Die Erfindung erzielt eine Verbesserung gegenüber den bekannten Anordnungen dadurch, daß eine mit demBrennraum durcheineodermehrereDrosselöffnungen in Verbindung stehende Kammer vorgesehen ist, in die die Elektroden einer Zündkerze oder der Glühdraht einer Glühkerze hineinragen und durch deren Drosselöffnung der zur Bildung des Zündgemisches dienende Brennstoff vom Zylinderraum her eingespritzt wird. Durch diese Zündherdkammer wird der durch das Aufspritzen zerstäubte und durch die Wärme des Kammermaterials aufbereitete Brennstoff gut in der Nähe der Elektroden zusammengehalten, so daß eine sichere Zündung gewährleistet ist. Infolgedessen schlägt das in der Zündherdkammer gezündete Gemisch in Form einer energischen Zündflamme in den Brennraum über, so daß die Verbrennung des Brennrauminhalts von der Zündkammermündung nach allen Seiten gleichmäßig und schnell fortschreitet.The invention achieves an improvement over the known arrangements in that one communicates with the combustion chamber through one or more throttle openings standing chamber is provided in which the electrodes of a spark plug or the glow wire a glow plug protrude and through its throttle opening to form the ignition mixture serving fuel is injected from the cylinder space. Through this ignition hearth chamber becomes the atomized by the spraying and by the heat of the chamber material treated fuel well held together near the electrodes so that safe ignition is guaranteed. As a result, it hits the ignition hearth chamber ignited mixture in the form of an energetic pilot flame into the combustion chamber, see above that the combustion of the contents of the combustion chamber from the ignition chamber opening on all sides progresses evenly and quickly.
Zündkerzenkammern mit Drosselöffnungen sind an sich, auch bei Einspritzbrennkraftmaschinen, bekannt.Spark plug chambers with throttle openings are per se, even in internal combustion engines, known.
In Ausgestaltung des Erfindungsgedankens wird vorgeschlagen, die Einmündung der Kammer in den Brennraum zum besseren Auffangen des Brennstoffstrahls und zwecks besserer Verteilung des austretenden, gezündeten Gemisches im wesentlichen trichterförmig in Richtung nach dem Brennraum zu erweitern.In an embodiment of the concept of the invention, it is proposed that the confluence the chamber in the combustion chamber for better collection of the fuel jet and for the purpose better distribution of the emerging, ignited mixture, essentially funnel-shaped to expand towards the combustion chamber.
Ferner bringt es Vorteile, die Einmündung der Kammer in den Brennraum als schräg in bezug auf die Kerzenachse verlaufende, gegen die Einspritzdüse gerichtete Bohrung auszubilden. Hierdurch wird z. B. das lästige Naßwerden der Kerzenelektroden vermieden, da diese außerhalb der Richtung des Einspritzstrahls liegen.There are also advantages in the opening of the chamber into the combustion chamber as running obliquely with respect to the candle axis and directed towards the injection nozzle Form bore. This z. B. the annoying wetting of the candle electrodes avoided, as these lie outside the direction of the injection jet.
DieZeichnung veranschaulicht schematisch einige Ausführungsbeispiele des Erfindungsgegenstandes, wobei Abb. i die Anordnung am Zylinder und Abb.2 und 3 günstige Formen der Kammermündungen zeigen.The drawing schematically illustrates some embodiments of the subject matter of the invention, with Fig. i the arrangement on the cylinder and Fig.2 and 3 show favorable shapes of the chamber mouths.
Gemäß Abb. 1 sind i der Zylinder einer Brennkraftmaschine, 2,die Einspritzdüse und 3 die Zündkerzen. Die Elektroden der Kerzen, sind mit 4 bezeichnet. Der Kerzenmantel ist über die Elektroden hinaus verlängert (bei 5) und umschließt einen Raum 6, welcher als Zündherdkammer dient. Die Zündherdkammern sind über Bohrungen 7 mit dem Zylinderbrennraum verbunden. Die Einspritzdüse 2 ist derart ausgebildet, daß ein Kraftstoffstrahl auf die Mündung der Zündherdkammer gerichtet wird. Mit Rücksicht auf diese Art der Kraftstoffzuführung wird die Zündherdkammermündung in entsprechender Weise gestaltet. Vor allem wird die Achse der Mündungsbohrung vorteilhaft so gelegt, daß sie etwa in Richtung des ankommenden Kraftstoffstrahls und vorteilhaft gegen die Kerzenachse geneigt verläuft. Das ist an den verschiedenen Kerzen in der Abb. i besonders deutlich sichtbar.According to Fig. 1 i are the cylinder of an internal combustion engine, 2, the injection nozzle and 3 the spark plugs. The electrodes of the candles are marked 4. The candle mantle is extended beyond the electrodes (at 5) and encloses a space 6, which serves as ignition hearth chamber. The ignition hearth chambers are connected to the cylinder combustion chamber via bores 7 tied together. The injection nozzle 2 is designed such that a fuel jet is directed at the mouth of the ignition hearth chamber. With regard to this type of Fuel supply, the ignition hearth chamber mouth is designed in a corresponding manner. In particular, the axis of the mouth bore is advantageously placed so that it is about in the direction of the incoming fuel jet and advantageously against the candle axis runs inclined. This is particularly clear from the various candles in Fig. I visible.
Weitere günstige Formen der Kammermündung sind in den Abb. 2 und 3 angedeutet. In Abb. 2 ist die Mündung nach außen hin trichterförmig verbreitert, wobei die T'richterachse etwas schräg gelegt ist, in der Annahme, daß die Kerze etwa in der Richtung des Pfeiles y angespritzt wird. In der Abb.3 ist die Kammermündung ungefähr halbkugelig nach außen verbreitert.Further favorable forms of the chamber mouth are shown in Figs. 2 and 3 indicated. In Fig. 2 the mouth is widened to the outside in a funnel shape, whereby the T'richterachse is placed somewhat obliquely, on the assumption that the candle is injected approximately in the direction of arrow y. In Fig.3 is the mouth of the chamber approximately hemispherical widened outwards.
Selbstverständlich können je nach dem einzelnen Fall Abweichungen von den hier vorgeschlagenen Formen zur Anwendung gelangen. Ebenso kann das Innere der Zündherdkammer gestaltlich dem einzelnen Bedarfsfall angepaßt werden.Of course, there may be deviations depending on the individual case of the forms proposed here are used. So can the interior The shape of the ignition hearth chamber can be adapted to the individual case of need.
An Stelle der Zündkerze kann gegebenenfalls auch eine elektrische Glühkerze verwendet werden.Instead of the spark plug, an electrical one can also be used Glow plug can be used.
